WRENCH.

Specification of Letters Patent.

Patented July 4, 1916.

Application filed-December 15, 1915. Serial No. 68,941.

T all whom it may concern:

Be it known that I, MERRILL C. RAIKES, a citizen of the United States,residing at Philippi, in the county of Barbour, State of Vest Virginia,have invented a new and useful rench; and I do hereby declare thefollowin to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to an improved wrench, and an object of theinvention is to provide a device of this nature, in which eificient,practical and improved features of construction are involved.

Another object of the invention is to provide a quick adjustable wrenchjaw, which is slid-able upon the shank of the cooperating jaw, and isprovided with a pivoted handle having teeth to coiiperate with teeth ofthe other handle, to hold the sliding jaw in adjusted position.

Another object of the invention is to provide spring means to hold thepivoted handle in close engagement with the other handle, as the wrenchis in use, thereby preventing the pivoted handle from separating.

In practical fields the details of construction may necessitatealterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts, ashereinafter set forth, shown in the drawings and claimed.

In the drawings: Figure 1 is a view in perspective of the improvedwrench constructed in accordance with the invention, showing the jawsseparated, and the two handles in contact. Fig. 2 is a view inperspective of the wrench showing the pivoted handle swung open. Fig. 3is a view partly in section and partly in elevation, showing the jawsseparated and illustrating the handles closed. Fig. 4. is a sectionalview on line 4.- 1 of Fig. 3. Fig. 5 is a detail view of portions of thetwo handles showing the cooperating teeth 3 and 25.

Referring more especially to the drawings, 1 designates the stationaryjaw having a shank 2, which constitutes a handle, and upon one face ofthis shank a series of teeth 3 is-provided. The opposite side faces ofthe shank 2 are provided with longitudinally arranged elongated ribs 4.A movable jaw 5 is provided having a rectangular opening 6, throughwhich the shank 2 of the jaw 1 extends. Opposite walls of this opening 6are provided with grooves 7, which receive the ribs 4. The jaw 5 isprovided with a socket 8, in which the lug 9 is pivoted upon the pin 10.This socket 8, as shown in Fig. 3 is angular, so that the walls 11 and12 will limit the lug 9 of the handle 12 in either direction. Where thesocket 8 is formed, the jaw is curved as shown at 13 upon an arc, usingthe pin or bolt as a center. The lug 9 projects from the curved surface14. of the pivoted end of the handle 12*, which curved surface 14: isconcentric with the curvature 13, so that the two surfaces will slidablyengage, as the handle 12 is swung open as shown in Fig. 2. The pivotalend of the handle 12 has a lip 15 overlying the curved part 13 of thejaw 5. The outer surface of this lip is curved as shown at 16, and isprovided with a notch 17 Pivoted between the lugs 18 of the jaw 5 uponthe pivot 19 is a dog 20, the nose '21 of which engages the notch 17 sothat by the action of the spring 22 (which is interposed between thetail end 23 of the dog and the rear portion of the jaw 5) the handle 12-is held against the shank or handle 2, thereby preventing the handle 12from swinging open while the wrench is being used. The handle 12 isprovided with teeth 25, adapted to cooperate with the teeth 3 of theshank or handle 2, so as to hold the movable jaw in different adjustedpositions. When the handle 12' is opened. it is necessary to depress thetail end 22 of the dog, so as to permit the nose of the dog to engagethe curved surface 16 of said lip, and between the two flanges 26.

The invention having been set forth, what is claimed as new and usefulis:

1. In combination, a stationary jaw having a handle or shank, a movablejaw slidable upon the shank, said shank having a series of teeth uponits inner face, the rear portion of the movable jaw having a socket andprovided with a semicircular curved part where the socket is formed, asecond handle having a curved end surface and a lip coiiperating withthe circular curved portion of the movable jaw, and provided with a lugpivoted in said socket, said sec ond handle having teeth to cooperatewith the teeth of the shank or first handle.

2. In combination, a stationary jaw having a handle or shank, a movablejaw slidable upon the shank, said shank having a series of teeth uponits inner face, the rear portion of the movable j aw having a socket andprovided with a semi-circidm curved part where the socket is formed, asecond handle having a curved end surface and a lip cooperating with thecircular curved portion of the movable jaw, and provided with a lugpivoted in said socket, said second handle having teeth to cooperatewith the teeth of the shank or first handle, said lip upon its outersurface having a notch, and a spring tensioned dog having its noseengaging said notch, to hold the piYoted handle against the shank of thestationary aw, said pivoted handle ad aQent the lip being provided withside flanges, between 15 which the nose end of the dog engages, whendisengaged from the notch.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
